CLEANFEED
Field of Application Statement running the printer's feed mechanism.
Syntax CLEANFEED
Chapter 2 Program Instructions
is the feed length expressed as a positive or negative number
of dots.
Remarks The CLEANFEED statement activates the stepper motor that drives the
printer's pressing roller (the rubber roller beneath the printhead). In case of
thermal transfer printers, it also often drives the ribbon mechanism. The
motor will run regardless of possible error conditions, e.g. if the printhead is
lifted or not, or if there is no ribbon or paper supply left.
Thus, the CLEANFEED statement is suitable for cleaning and for the loading
of transfer ribbon.
A positive CLEANFEED value makes the stepper motor rotate the rollers
forward, i.e. as when feeding out a label.
A negative CLEANFEED value makes the stepper motor rotate the rollers
backwards, i.e. as when pulling back a label.
The execution of a CLEANFEED statement, as opposed to TESTFEED,
does not affect the adjustment of the label stop sensor or black mark sensor,
regardless what type of media or other objects that passes the sensor.
Note that the CLEANFEED statement, as opposed to FORMFEED, always
must be specified in regard of feed length.
Example In order to pull a cleaning card back and forth under the printhead three
times, three 1200 dots long positive CLEANFEEDs and then the same
amount of negative CLEANFEEDs are performed:
10 FOR A%=1 TO 3
20 CLEANFEED 1200
30 CLEANFEED -1200
40
